  • 1.  PIPEDDR Issue

    Posted Thu October 12, 2023 12:36 PM

    hi,

    Has anyone come across issues with the z/VM 7.2 and PIPEDDR 1.7.9

    We are backing up a 3390-3 Disk using PIPEDDR under z/VM and restoring at our DR site. The physical dasd is different but still 3390-3.

    We can restore z/VM volumes with no issue and 3390-3 that have been backed up using CMSDDR option but for system packs we use pack type digest sha256.

    When restoring under z/VM we are getting LABEL read issues which causes a failure. This only occurs at our DR site on not when restoring at our main site.

    FPLDA81256E Cylinder number 0 beyond disk capacity 0               
    FPLSCA004I ... Issued from stage 1 of pipeline 1 name "readlab"    
    FPLSCA001I ... Running "trackread 3100 0 0 1"                      
    Novalue raised at line 3739 of PIPEDDR.                            
    The variable referenced is LABEL                                   
    HCPDAS537A  DASD  3102 THE LABEL COULD NOT BE READ   

    We are at a lose as to how to fix this.

    Any help appriecated 

    Dave
